LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 774,015, dated November1, 1904.

Application filed .Tune 27, 1901. Serial No; 66,249. (No model.)

To @ZZ whom, it may concern.-

Be it known that I, JOHN T. WILSON, a citizen of the United States,residing at Jersey Shore, in the county of Lycoming and State ofPennsylvania, have invented new and useful Improvements in Lubricators,of which the following is a specication.

The object of my invention is generically the provision of means forintermittently transferring oil, ac., from a receptacle or pipe to anopening or to another pipe or receptacle of any kind.

A further object and specifically is the provision of means forintermittently deliveringa lubricant, such as oil, to the valve of anengine.

A further object is the provision of means for intermittentlydeliveringr oil to the valve of a locomotive-engine and removing thewater or water and oil which sometimes forms a plug above the pointwhere the ordinary oil-pipe enters the steam-chest and the provision ofadditional means whereby the oil from the oilpipe will be delivered tothe valve when the throttle is closed and the locomotive moving underthe action of gravity or by its own momentum.

Tith these ends in view my invention consists, objectively, in a casingor cylinder or the like having ports, a movable element, as a plunger,within the casing and actuated by fluid-pressure, said movable elementor plunger being adapted intermittently to transfer fluid from one ofthe ports to the other port and means for cushioning the movable elementat both ends by uid under pressure.

It further consists in the combination, with a locomotive-enginecylinder and steam-chest, of a device for intermittently delivering oilor oil andwater from the oil-pipe to the valve and means independent ofthe action of the delivery device for allowing the oil to pass directlyto the Valve at all times.

Finally it consists in certain novelties of construction andcombinations of parts hereinafter set forth and claimed.

The accompanying drawings illustrate one example of the physicalembodiment of my invention constructed according to the best mode I haveso far devised for the practical application of the principle.

Figure 1 shows in dotted lines the cylinder and steam-chest of alocomotive-engine and in full lines my means for delivering iuidsassociated therewith. Fig. 2 is a sectional view of the fluid-deliverydevice with the pipes detached. Fig. 3 illustrates the movable elementor plunger. Fig. 4t isa section of Fig. 2, taken on the dotted line.

Referring to the several figures of the drawings, the letter Adesignates a cylinder; B, the threaded ends of the cylinder; O, a portthrough the wall of the cylinder; D, a similar port located in anotherpart of the cylinderwall; E, a cored passage in the cylinder-wall whichunites the two ports; F, a groove in the inside surface of the cylinderand in line With port C, as shown; G, a similar groove in line with portD and in this case parallel with the first-mentioned groove; H, thecylinder-heads;I, ports in the heads: J, guidingstems on the heads; K,longitudinal passages through the stems; L, cross-passages; M, a movableor reciprocating plunger; N, a groove in the external surface of theplunger, which may be of the shape shown-that is, one of the surfacesbounding the groove is plain and at right angles to the length of theplunger and the other surface curved; O, central holes in the plunger,both in line and each open at one end; P, longitudinal passages throughthe plunger; Q, a locomotive or other engine cylinder; R, thesteam-chest; S, pipes uniting the ends of the locomotive-cylinder andthe ends of the cylinder A of the delivering device; T, a connectionuniting the fluid-deliverer and steam-chest and provided with an openpassage, and U is the oil-pipe, which may lead from a sight-feedlubricator vor other source of oil-supply.

The operation of the device is as follows: Steam or other motive fluidbeing admitted to the port which is open to the left-hand end of theengine-cylinder, the same passes through pipe S at the left and forcesthe plunger to the position shown in Fig. 2. When the plunger is movingfrom the left toward the right and uncovers the cross-passage L, steamhas access to the opposite end of the cylinder A by way of the passagesP P and forms a cushion which prevents the IOO end of the plungerstriking at all or violently striking the cylinder-head. As is well unlderstood, steam is simultaneously being eX- hausted from the right-handend of the eni gine-cylinder while it is being' admitted to l theleft-hand end. The pipe S at the right is therefore open to theexhaust-port of the engine while the plunger is moving from the l lefttoward the right, and hence there is no l resistance offered to themovement of the plunger. lt is obvious that when live steam is admittedto the right-hand end of the cylinder the plunger will be moved towardthe left and the pipe S at the left be in commu nication with theexhaust. The result is that at everystroke of the engine-piston theplunger M will move simultaneously and in the same direction the lengthof the casing or cylinder A. In locomotive practice when the throttle isclosed and the locomotive is moving downgrade or by its own momentum thepiston will compress the air within the cylinder and at opposite endsalternately and the plunger will be actuated and move in the directionopposite to the movement of the engine-piston. The plunger willtherefore be operated in locomotive practice under all conditions. Now,referring to Fig. 2, it will be seen that when the plunger is at theleft end of the cylinder A the groove N will register with the port Cand that whatever oil or oil and water may be in the pipe U will pass tothe groove N by gravity. hen the plunger moves to the right, the fluidin groove N is carried along and delivered into port D as soon as thegroove N registers with groove Gr. The groove F allows fluid underpressure in pipe U to pass all around the plunger, and

thus balance it.

The function of the cored passage is to deliver oil from pipe U tothesteam-chest at all times whether the locomotive is or is not working'steam. In locomotive-engine practice a water-plug often forms just abovethe opening of the pipe U into the steam-chest. My liuid -deliveringdevice will vremove the water and oil, or either, and insure a uniformdelivery of' oil to the valve under all conditions.

l/Vhile I have specifically illustrated and described only one exampleofl the physical embodiment of my invention and that in connection witha locomotive-engine, l by no means intend to restrict the scope to suchpictured or specific example or application, inasmuch as the principlecan be applied by different modes and for other specific purposes. Thenecessary elements for the application ofl the principle are a casing orthe like, a movable element actuated by fluidpressure, means forcushioning the movable elements, a source of fluid-supply which is to betransferred in communication with the movable element in one of' itspositions, and

an opening or pipe which communicates with the movable element atanother position which it occupies relative to thecasing. Thearrangement should be such that at each cycle of its movement themovable element shall intermittently transfer fluid from one place toanother. When the invention is used in connection with a stationaryengine, the pasi sage E or its equivalent may be omitted, and

in certain cases it may be omitted when used in connection withlocomotive-engines, if so desired. The delivering device is obviouslyadapted for use with a sight-feed or other type of lubricator or withany reservoir and for any purpose where fluid is to be intermittentlydelivered from any source to a pipe or opening or any receptacleWhatever.

The modifications in structure and arrangement and the additions andomissions necessary in adapting the device for diiferent specilicpurposes or objects will readily be understood by persons skilled in themechanical arts. A What I claim as new, and desire to secure by LettersPatent, is-

l. The combination of a casing having supply and delivery ports; areciprocating element in the casing having a groove which alternatelyregisters with the supply and delivery ports; means for containingmotive fluid under variable pressure; and means connecting the ends of'the casing with the means for containing motive fluid under variablepressure; the casing and reciprocating element being provided withpassages, whereby motive fluid is interposed between the end of thereciprocating element and the casing at each stroke thereof' forcushioning the same.

2. The combination with a locomotive-engine, of' an oil-pipe; means forpositively and intermittently delivering oil from the oil-pipe to thesteam-chest when the locomotive is working steam; and a cylinder-casingcontaining the positive operating means uniting the oil-pipe andsteam-chest and having a passage open at all times for allowing oil topass from the oil-pipe to the steam-chest when the locomotive is movingby its own momentum or under the action of gravity.

3. The combination with an engine, of' an oil-pipe; means forintermittently delivering oil from the oil-pipe to the steam-chest, saidmeans being actuated by the motive liuid which moves the piston of theengine; and a supplemental conduit connecting the oil-pipe to thesteam-chest, said conduit being continually open under all conditionsofl service.

4. The combination of' an engine-cylinder; a casing having ports; aplunger in the casing having a groove which alternately registers withthe ports; means uniting' the engine-cylinder and the ends of the casingfor the passage of motive fluid; an oil-supply pipe; and a steam-chestin communication with the casing by means of the connection, T; saidcasing having a passage in the wall thereof open at all times Jfor theflow of oil.

IOO

5. The combination with a casing having supply and delivery ports, of anelement having a groove and movable in the casing and actuated by motivefluid, said g'roove being in communication with only one port at a time;and means connecting the casing with means containing motive fluid foractuating the movable element; the construction being such that themotive Huid which actuates the movable element is introduced betweenAthe movable element and each end ofthe casing alternately for cushioningthe movable element.

6. The combination in a lubricator, constructed and operatingsubstantially as set forth, of a casing having inlet and outlet ports;cylinder-heads having ports; a plunger, and having a groove adapted toregister alternately With the ports in the casing, located in thecasing; additional means for guiding the plunger; and means forintroducing motive fluid tothe opposite ends of the plunger; saidplunger having passages for motivefluid, whereby motive fluid may passfrom one end of the plunger to the other end and cushion the plunger.
